Hovering over an NLS message doesn't show the contents if the bundle name isn't constant

[kjsmita6]

Introduction

When creating a message bundle using the "Externalize strings wizard", the java class is initialized with a BUNDLE_NAME variable which contains the fully-qualified name of the message properties file, like:

private static final String BUNDLE_NAME = NlsDemoMsg.class.getPackageName() + ".nlsdemomsg"; //$NON-NLS-1$

In this case, it would resolve to com.example.jdt.nls.msg.nlsdemomsg which indeed resolves to a file called nlsdemomsg.properties in the com.example.jdt.nls.msg package.

Problem

When using any messages from a class created in this way, hovering over the message does not show the contents, and you are not able to quickly goto it in the properties file:

I am assuming this is PDE's version of the wizard since it uses org.eclipse.osgi.util.NLS instead of ResourceBundle, but the plain-old Java version does the same thing, using Messages.getString("key") instead. The hover and goto only work if the BUNDLE_NAME is a constant string.

Workaround

If the BUNDLE_NAME is changed to be just the string itself, like

private static final String BUNDLE_NAME = "com.example.jdt.nls.msg.nlsdemomsg"; //$NON-NLS-1$

then those things work:

Expected

Ideally these features would work in all cases, especially as the wizard that makes this file does it the first way by calling getPackageName().
